SFP Transceiver Modules

An SFP module is a small transceiver (transmit and receive data) plug that fits into an SFP socket on a network switch, media converter, inline card, etc. SFPs allow you to choose the type of interface you need for a particular application without having a hard-wired port on your device, giving flexibility and plug-and-play ease of use.
